Application filed May 11,

My invention relates to transformers and to other fluid-cooled apparatus having detachable radiator elements employed in connection therewith, and it has particular relation to valves adapted to be utilized to close the communication between the main tank and the radiators to facilitate the removal of the latter for the purpose of re-' placement or repairs.

Hereto'fore, in certain types of apparatus, and particularly in large transformers employing detachable radiator elements, considerable difficulty and inconveniencewere encountered when it became necessary to re move a radiator element for any purpose, such as to repair leaks, by reason of the fact that it was necessary to first entirely empty the main tank and all of the communicating radiators of the fluid contained therein.

This removal of the oil or other fluid necessitated. the utilization of a large number of barrels or other containers and usual,- ly resulted in the loss of a considerable quantity of oil.

One of the objects of my invention is to provide a valve which is particularly adapted to close the communication between the main tank and the radiator elements, thereby rendering it unnecessary to remove the fluid contents of the tank and other radiators when one of the radiators is removed for the'purpose of repairs.

Another object of the invention is to provide a valve of compact construction that may be installed in connection with transformers of standard types and by employing relatively few connecting joints.

A further object of my invention is to provide a device of the class described that may be quickly and easily operated and that may be manufactured at a relatively small cost.

The single figure of the accompanying drawings is a vertical longitudinal sectional view through a portion of a transformer tank and radiator connections, the radiator element being shown in elevation.

Referring to the drawings, 1 indicates a portion of a transformer tank comprising a cylindrical side wall 2 a top 3, and a bottom 4. A radiator element, illustrated as comprising a plurality of spaced and parallel vertically-extending envelopes 5 conacted at the upper and lower extremities TRANSFORMER RADIATOR VALVE.

thereof by means of header members 6, suitably mounted exteriorly of the tank 1 for communication therewith.

Inasmuch as the construction of the upper and the lower communicating means are substantially similar, a description otone. of them will be sui'licient.

The header men'ibers 6 are preferably connected to the main tank 1 of the tra. dormer for communication therewith by means of elbow members 7, each of which has an outwardly-extending fiance 8 at its end adjacent to the tank. The finage 8 is preferably clamped, by bolts 9, to a coupling member 10 which is suitably secured to a relatively short tubular section 11 carried by the tank.

The member 10 is provided with an interiorly screw threaded aperture 12 into which is screwed a valve seat 13 which extends within the tubularmember 11, and in spaced relationtherewith. The" valve 13 is preferably interiorly screw threaded, as at 14, to engage a similar screw-threaded valve member 15. The seat 13 is further provided with a plurality otside apertures 16 adjacent to the inner end thereof which constitutemeans ot'comi'nunicaltion between the memberll and the radiator.

An operating rod or handle 17 removably engages the valve 15 andextends through the elbow 7 and out through screw-threaded nipple 18. 'A cap 19, provided with a suitable packing 20, is provided for the nipple 18 and entirely encloses the end of: the rod 17 when the rod occupies its innermost position, thus preventing leakage at the point where the. rod merges from the elbow 7 An aperture or port 21 which constitutes a means for draining the radiator prior to detaching the same is normally closed by means of a screw threaded plug 22.

When the radiators are secured in position with respect to the tank, under normal operating, conditions, the valves 15 are moved to their innermost positions, as illustrated in the upper portion of the drawing. In this position, the fluid contained in the tank 1 may pass freely through the 1 apertures 16 in the valve seat 13 and through the elbow 7 into the radiator element for free circulation therethrough. If it is desired, however, to detach the radiator for any purpose, the caps 19 are removed to provide access to the rods 17. The rods 17 are then so manipulated as to screw the valve members 15 outwardlv into the positions illustrated in the lower portion of the drawing in which positions connnunication bet veen the snain tank and the radiator through the parts 16 is interrupted.

The plugs 22 at the upper and the lower portions ot the radiator are then removed, allowing the oil or oth r tlnid to be drained from the 'adiator through the lower aperture and. at th same time. permitting; air to enter through the upp aperture. T he bolts 9 may hen oe remmed and the radianed troni the transformer tor element the tank. ll hen the 1-(,it1t01. is detached tron the. tank. the rods 17 norte-d within the elbows 7 iv meansv ot the nipple l8 and a suitable spider or guide From the foregoing descriptioi it apparent that the necessit; large number of cor i e p i oul neces 0 provide a relativel v small container tie tiuid contents ot the radiator that is to be detached.

What I claim as my invention is:

1. A transformer tank having a detachable adiator element mounted thereon, tubular coupling members disposed between said tank and said radiator to establish communication therebetween at the upper and lower portions thereof, valve seats disposed within said coupling nembers each provided with ports though which com munication is established between said tubular members and said raoiator, a valve cooperating with each of said valve seats and adapted to int rrupt the connnunicatioi through said ports and means tor actuating said valve.

A tlilLS'lOlDlGl tank havinga detacln able adiator element mounted thereon tubular coupling members disposed between said tank and said radiator to establish communication therebetwecn at the upper and lower portions thereof, valve seats facing said tank, disposed within said coupling men'ibers and provided with ports through which conm'iunication is e tablished between said tubular members and said radiator. a valve co-ope *ating with 0; ch of said valve seats and adapted to interrupt the communication tbruigh said ports, and means for actuating the valves.

A transformer tank ha ing a detach able radiator element nurunted thereon. tubular coupling members d sposed between said tank and said 'adiator to establish comn'iunieation therebetweeu at the upper and lower portions thereof. valve seats Facing said tank, disposed within said coupling members and provided with ports, zhrou zh which communication is estal/ bed between said tubular members and saiu radiator. a valve co-operating with each of said valve seats and a-tapted to be moved rmtwardly from said tanl: into the ab'e seats to interrupt the con'm'iunication through said ports. and means for actuating the valves.

a it transformer tank having a detachable adiator element mounted thereon tubulacoupling members dispo between said tank and said radiator to establish communicz'itien therebetween at the upper and lower portions thereof valve seats tacin r inwardly relative to said tanle disposed within said coupling members through which comn'iunication established betv-reen sa d tubular members and said 'adiator. a valve co-operating with each of said valve seats and adapted to be moved outwardly relative so said tank into the valve seats to interrupt communication between the tank and the radiator, and means for actuating the valves.

In testimony whereof, I have hereunto subscribed my name this 29th day of April, 1921.
